Dab tsi yog cov tswv yim tseem ceeb rau kev txhim kho thiab tswj cov rooj vag li cas?

Raws li cov khoom siv tseem ceeb rau kev tswj cov kua dej ntws hauv cov tshuab raj, lub installation, lub installation thiab tu tau zoo ntawmRooj vag Li Qubyog cuam tshuam nrog kev ruaj khov thiab kev nyab xeeb ntawm cov haujlwm ua haujlwm. Hauv qab no yog cov txheej txheem tseem ceeb:

1. Install theem: Ua ntej, ua kev soj ntsuam thiab kev kho mob kom paub meej tias tusrooj vag valveQauv, Siab Ntsuam, Cov Khoom Siv, thiab Kev Ua Haujlwm Cov Lus Sib Tw, thiab tsis muaj kev thauj mus los. Ntxuav cov raj xa hluav taws xob, thiab ua yeeb yam airtightness thiab kev xeem ua rau cov haujlwm tseem ceeb. Thib ob, them sai sai rau cov kev taw qhia thiab txoj haujlwm, nruab raws li cov ntawv qhia xub. Qhov ntsug lub valve qia yuav tsum txiav mus rau hauv av, thiab kab rov tav inclination yuav tsum yog 15 °. Reserve chaw rau Handwheel lossis Actuator kev ua haujlwm (≥ 300mm). Thaum sib txuas thiab kho, cov flange kev txuas yuav tsum tau ua kom raws li lub qhov ntsia kub thiab zom cov theem; Siv Argon arc vuam raws li lub hauv paus rau kev sib txuas vuam txuas thiab maj mam txias. Thaum kawg, kev ua txhaum kev ua txhaum thiab kev lees txais, qhib thiab kaw 3-5 zaug, saib seb nws ruaj khov nrog xab npum lossis siab ntsuas.

2. Kev kho mob theem: Kev soj ntsuam txhua hnub yuav tsum kuaj xyuas lub rooj vag valve, sau tus naj npawb thiab sijhawm qhib, thiab kho cov kev txawv txav. Nyob rau hauv cov nqe lus ntawm lubrication thiab sealing, siv cov pa hluav taws xob siab rau lub rooj vag ua ntej kev kaw suab sib dhos Kev tu ib txwm muaj yuav tsum tau nqa ib zaug txhua txhua 6-12 lub hlis rau kev ua haujlwm ib txwm muaj thiab ib zaug txhua 3 lub hlis rau kev ua kom huv lossis kub ua haujlwm. Yog hais tias cov npoo sib khi hnav, lub valve lub qia yog khoov, lossis cov ntaub softage tshaj tus qauv, nws yuav tsum tau hloov. Hais txog kev daws teeb meem, yog tias muaj dej xau sab hauv, bolts tuaj yeem nruj lossis sib foob tuaj yeem txhaj. Yog tias nws yog mob hnyav, lub rooj zaum hauv valve tuaj yeem hloov; Soak lub valve kav hauv loosening tus neeg sawv cev lossis rhuav tshem thiab ntxuav nws yog tias nws tau daig. Nyob rau hauv cov kev ua haujlwm tshwj xeeb, nruab cov pob qij txha nthuav dav nyob rau hauv cov kev mob siab thiab siv cov khoom kub siab resistant; Tsawg qhov kev kho kub tsawg yog nqa tawm hauv qab cov kev mob tsawg-tsawg, thiab txuas ntxiv valve valve yog xaiv; Corrosive tawm Media nrog cov khoom siv los tiv thaiv corrosion, nquag xeem rau PH tus nqi.

Cov lus qhia rau kev zam cov pitfalls: Ua raws li cov kev ntsuas ntws ntawm lubrooj vag valve; Valve lub qhov ntsia ≤ RA0.8 μ m; Qhwv lub cev valve lossis muab kev tiv thaiv nitrogen ua ntej vuam. Cov qauv kev teeb tsa thiab kev tshawb fawb tuaj yeem txuas ntxiv cov kev pabcuam lub neej ntawm ntau dua 50% thiab txo tus nqi tsis ua haujlwm. Nws raug nquahu kom tsim cov cai thiab cov neeg qhia ua haujlwm raws li phau ntawv.
